It is propressure on theincoming material. This is 9 vided with a central shaft O, having theoreffected by causing the bottom of the plunger dinary knives, which pugthe clay or other S to rest on the upper surface of a .small 45 materialwhile traversing it toward the mouth platform T, which is forceddownward by of the mill. The driving of the pug-mill the pressure of theclay coming from the shaft is efiected through the medium of twopug-mill, the movement of the platform T elliptical toothed wheels D andF, of which being regulated by the cam Q, operating through the levers Zand Y. the rocking shaft IV, the lever X, and the link V, all connectedtogether by suitable pivots. The platform T is inclos'ed within a casingU, in which it is guided to reciprocate vertically. A pivoted link N isprovided to secure the proper move ment of the upper end ofthe lever Z,which also is provided with a roller where it adjoins the cam Q. Thiscam Q, attached to the end of the shaft M, is so set in relation totheelliptical wheels D and F that it allows of the plunger S descending atthe time when the pug-mill shaft has its quickest rotation, and whentherefore it extrudes the material quickest from the pug-mill.

After the mold is filled with compressed clay it is drawn away from themouth of the pug-mill by the action of the lever g, the link f, and theslotted drum or cam k, carried by the shaft M. The link is pivoted inone end a of the mold-box (Z and connected at its other end to the leverg, which is pivoted so as to oscillate about the spindle it, the otherend being provided with a bowl 11, which works in the irregular slot 7'of the drum k and is so set in regard to the elliptical wheels D F thatwhen the pug-mill shaft is decreasing in speed the mold boX is drawnaway. The movement of the mold-box sidewise causes the parting of theclay stream by the triangular side bars on m, held in place by thecross-bars a a, which in their turn are secured by the bolts 0 passingthrough the brackets 11, attached to the ends of the outlet. As the moldR is pulled away, its place beneath the pug-niill mouth is taken by theback part of the mold-box (Z, provided with a facingplate 0. At the sametime the plunger S is drawn across the top of the platform-T, and

upon reaching the other side it is immediately raised in the mold by thefurther action of the cam Q and the connecting-levers.

The mold-box is provided with sliding surfaces 5 b, which slide over thesurfaces (1 a, formed on the casing U. The mold itself is formed withliners, which can be renewed by unbolting a removable side which isprovided on the mold-box.

After being raised level with the table by the rise of the platform andplunger before mentioned the clot of clay is caught by the rake a andpassed onto the table 1 of the press proper. The mechanism by which therake '2' is operated consists of a cam fl/ on the shaft M, whichactuates levers w and o, piv oted on the spindle 20, so that the bottomend of the lever o is reciprocated backward and forward. To it, by meansof the link it, is connected a piece 3. to which the rake r is attachedand which slides on the slide-bar t, secured in a suitable position bybolting to V brackets on the framework of the machine.

In order that the bowl of the cam-lever a? shall remain in contact withthe face of the cam, a rod 10 is connected at one end to the lever e andat the other end to a spring 2. interposed between the said head and afixed part of the machine-frame, so that the spring is always incompression, and thus keeps the bowl against the cam.

The rake '2' pushes the clot onto the table 1 of the press, where itremains until the succeeding clot is formed, when it is pushed over themold 2 by the next action of the rake and the succeeding clot, which inlike manner remains on the table until pushed forward by another clot.The clot is pressed in the mold 2 by the action of the cross-head 7 andthe plunger 3, Fig. 4E, operated by the eccentric 1, which presses theclot between the plungers 3 and 5. The brick is pushed out of the moldby the raising of the bottom plunger 5, connected to the cross-head bythe rods 6 6, and is pushed off the top face of the plunger when levelwith the table by the movement of the incoming clot.

In Figs. 5 and 6 is shown a modification of this invention in which aduplex arrangement is carried out, there being two presses fed from asingle pug mill, It will be seen that the arrangement of the left-handpress and the pug-mill is substantially the same as before; but anadditional press is added on the right-hand side with a duplicate set ofcam-and-lever mechanism 21 22 23 2e 25 for operating the platform andplungers of the reciprocating mold-box (Z. This mold-box is constructedwith two molds l7 and 18, each fitted with plungers and so placed thatone mold is being filled while the material is being pushed out of theother mold. In order that this may be accomplishethit will be seen onreference to Figs. 7 and 8 that the platforms 30 and 31, thoughcontained within one guideboX U, are raised or lowered by the leversXand 25 independently of each other and in accordance with the movementof the cams Q and 21 on the shafts M and 20, respectively, which are setin respect to each other so thatthe platform 30 is rising while 31 isfalling, and vice versa. In order to save space while obtaining asufficient length of platform to allow of the plungers remaining thereonand at the same time following the reciprocation of the mold-box, thesingle platform 31 is meshed into the double platform 30, which forms aguide for same in conjunction with cornerpieces 32, attached to thecorners of the plat form and working in recesses of the casting U. Inorder that the plungers shall not foul each other, the plunger in themold 17 is provided with two stems 26 and 27, carried by the outerportions of the platform 30, while the single stem 19 of the plunger inmold 18 is carried centrally on platform 31. Both platforms havebearing-plates which can be renewed when worn. The reciprocation of themold-box is effected as before by levers and a drum-cam l having asuitable slot cut in its circumference. In this case, however,

IIO

the drum-cam it is carried by the additional shaft 20. The operation ofthe rake to pass on the clots is also effected as before shown in Fig.3, an extra cam 33 being added on shaft 20 and similar mechanism tobring the alternate clots onto the table 28 of the righthand press. Byusing this device the necessity for elliptical wheels is removed, as thepug-mill can be feeding the molds almost continuously, and waste ofpower is thus prevented, while a larger output of bricks is secured.
